【Abstract】 A touch vibration feedback simulation teaching platform has been designed and implemented based on the domestic GD32 microcontroller unit(MCU). This platform utilizes the GD32 MCU to receive touch actions from the touchscreen via the RS232 serial port. By controlling the motion of a miniature linear vibration motor, it simulates the tactile sensation after touch.Additionally, the impact of different control parameters have been investigated, such as PWM frequency, duty cycle, and duration,on the effectiveness of tactile feedback simulation. The teaching platform exhibits good integration of key concepts, compact size,and an easy-to-experience experimental effect. It can be used for classroom demonstration experiments in electrical and electronic courses, undergraduate course design, and student innovation practices.更多还原
